Abstract
Description
- The invention relates to pressure vessels, and more particularly to a mounting system for a pressure vessel having an impact element.
- Fuel cells have been proposed as a power source for electric vehicles and other applications. In proton exchange membrane (PEM) type fuel cells, hydrogen is supplied as a fuel to an anode of the fuel cell and oxygen is supplied as an oxidant to a cathode of the fuel cell. A plurality of fuel cells is stacked together in a fuel cell stack to form a fuel cell system. The fuel is typically stored in large, hollow, substantially cylindrical pressure vessels disposed on an undercarriage of the vehicle.
- The pressure vessel is typically multi-layered and includes at least an inner liner and a filament wound outer layer. The pressure vessel is typically coupled to a frame or other structure of a vehicle in which the vessel is used. To provide the vehicle with a desired travel range and a vehicle appearance consistent with consumer needs, a plurality of the pressure vessels may be required. Conventional mounting systems typically include a plurality of circumferential bands fastened to a support structure. The mounting systems may be of considerable size and weight that may restrict service of the pressure vessel. Furthermore, conventional mounting systems do not allow for the movement of the pressure vessel in the event of a side or rear impact event. In the event of the side or rear impact event, the outer layer and/or the inner shell of the vessel may be breached, the restraining means may be irreparably altered, or the restraining means and pressure vessel may be caused to shift to an undesired angle or from a desired location to contact another component of the vehicle.
- It would be desirable to develop a mounting system adapted to absorb at least a portion of forces on the pressure vessel caused by a side or rear impact event without breaching the pressure vessel, altering the restraining means, or movement of the restraining means and/or the pressure vessel.
- Concordant and congruous with the present invention, develop a mounting system adapted to absorb at least a portion of forces on the pressure vessel caused by a side or rear impact event without breaching the pressure vessel, altering the restraining means, or movement of the restraining means and/or the pressure vessel has surprisingly been discovered.
- In one embodiment, a mounting system comprises a vessel shell having an end coupled to a first body; a mounting shell having an end coupled to another end of said vessel shell and another end coupled to a second body; and an impact element formed in one of said vessel shell and said mounting shell having a yield strength less than said vessel shell and said mounting shell.
- In another embodiment, a storage system for a vehicle, the system comprises a pressure vessel; a mounting system disposed on an end of said pressure vessel, said mounting system further comprising a vessel shell having an end coupled to the end of said pressure vessel, a mounting shell having a first end coupled to the vehicle and a second end coupled to another end of the vessel shell, and an impact element formed in one of the vessel shell and the mounting shell having a yield strength less than a yield strength of the vessel shell and the mounting shell; a clamping element for coupling the vessel shell to the pressure vessel; and a coupling means disposed adjacent the impact element for coupling the vessel shell and the mounting shell together.
- In another embodiment, A storage system for a vehicle, the system comprises a pressure vessel; a pair of mounting systems disposed on an end of said pressure vessel, each mounting system further comprising a vessel shell having an end coupled to the end of said pressure vessel, a mounting shell having a first end coupled to the vehicle and a second end coupled to another end of the vessel shell, and a plurality of impact elements formed in one of the vessel shell and the mounting shell having a yield strength less than a yield strength of the vessel shell and the mounting shell; another pair of mounting systems disposed on another end of said pressure vessel, each mounting system having a vessel shell having an end coupled to the end of said pressure vessel, a mounting shell having a first end coupled to the vehicle and a second end coupled to another end of the vessel shell, and a plurality of impact elements formed in one of the vessel shell and the mounting shell having a yield strength less than a yield strength of the vessel shell and the mounting shell; a clamping element for coupling the vessel shell to the pressure vessel; and a coupling means disposed adjacent the impact element for coupling the vessel shell and the mounting shell together.

FIGS. 1-6 illustrate astorage system 100 including a plurality ofmounting systems 10 and apressure vessel 12 according to an embodiment of the invention. Eachmounting system 10 includes amounting shell 14, avessel shell 16, and animpact element 18. It is understood that themounting systems 10 may be disposed between and coupled to a first body and a second body other than apressure vessel 12 and avehicle 26 as described hereinbelow. For example, one or more of themounting systems 10 may be coupled to and disposed between two internal components of a vehicle or other structure, or one or more of themounting systems 10 may be coupled between an internal component and thevehicle 26. - In the embodiment shown, a pair of
mounting systems 10 is fixed to each end of thepressure vessel 12 by a pair ofclamping elements 20. Theclamping elements 20 are rings adapted to couple themounting systems 10 to thepressure vessel 12 to militate against the relative movement between themounting systems 10 and thepressure vessel 12. Theclamping elements 20 may frictionally engage themounting systems 10 to couple themounting systems 10 to thepressure vessel 12. It is understood that theclamping elements 20 may be an elongate member having ends adapted to be mechanically fixed together to form theclamping elements 20 around themounting systems 10. It is understood that any number ofmounting systems 10 may be coupled to thepressure vessel 12, and any number ofclamping elements 20 may be used to couple themounting systems 10 to thepressure vessel 12, as desired. - The
pressure vessel 12 is formed by an inner liner (not shown) formed from a polymeric material and anouter layer 22 formed by a filament winding process. Thepressure vessel 12 has a substantially cylindrical shape and is adapted to hold a pressurized fluid (not shown). The inner liner of thepressure vessel 12 may be formed from a main body having a pair of hemispherical end caps fixed thereto, or thepressure vessel 12 may be formed from a unitary material, as desired. Once the inner liner is formed, theouter layer 22 is filament wound therearound. It is understood that thepressure vessel 12 may have any shape as desired, and thepressure vessel 12 may include additional layers such as a barrier layer, a foil layer, and the like, as desired. The pressurized fluid may be any fluid such as a gas such as hydrogen gas, compressed natural gas, and oxygen gas, a liquid, or both a liquid and a gas, for example. - The
mounting shell 14 includes afirst end 24 adapted to be coupled to the vehicle 26 (as best shown inFIG. 6 ) and asecond end 28 adapted to be coupled to thevessel shell 16. As best shown inFIGS. 1 , 2, 5, and 6, themounting shell 14 has a generally arcuate cross-sectional shape. Themounting shell 14 cross-sectional shape may be an arc of a circle, a semicircle, or a circle, as desired. Themounting shell 14 is formed from polymeric material such as a fiber-reinforced polymer, for example a sheet molding compound (SMC), but the mounting shell may be formed from another moldable material, such as a metal, a plastic, an alloy, glass, and the like, for example. Favorable results have been obtained from mountingshells 14 formed from glass fiber reinforced plastics. It is understood that the glass fibers may be randomly dispersed throughout the polymer, or the glass fibers may be aligned perpendicular to a longitudinal axis L of thepressure vessel 12 or parallel thereto. Thefirst ends 24 of themounting shells 14 include aflange 30 adapted to cooperate with a suitable fastener to mount themounting shells 14 of themounting systems 10 to a frame, aside rail 31, or other longitudinal beam or structure of thevehicle 26. It is further understood that themounting shell 14 may include additional unidirectional layers from one of the moldable materials, beads or fins, and/or webs of material adapted to militate against a buckling or theshell 14, as desired. - The
vessel shell 16 includes afirst end 32 adapted to be coupled to thesecond end 28 of themounting shell 14, and asecond end 34 abutting thepressure vessel 12. As best shown inFIGS. 1 , 2, 5, and 6, thevessel shell 16 has a substantially arcuate cross-sectional shape. Thevessel shell 16 cross-sectional shape may be an arc of a circle, a semicircle, or a circle as desired. Thevessel shell 16 is formed from a fiber-reinforced polymer, for example a sheet molding compound (SMC), but themounting shell 14 may be formed from another moldable material, such as a metal, a plastic, an alloy, glass, and the like, for example. Favorable results have been obtained fromvessel shells 16 formed from glass fiber reinforced plastics. It is understood that the glass fibers may be randomly dispersed throughout the polymer, or the glass fibers may be aligned perpendicular to a longitudinal axis L of thepressure vessel 12 or parallel thereto. It is further understood that thevessel shell 16 may include additional unidirectional layers from one of the moldable materials, beads or fins, and/or webs of material adapted to militate against a buckling or theshell 16, as desired. - As best shown in
FIG. 4 , theimpact element 18 is disposed intermediate a top surface and a bottom surface of themounting shell 14. Theimpact element 18 is defined as the portion of the material disposed across one of theapertures 36 formed in themounting shell 14 regardless of how eachimpact element 18 is formed. For example, eachimpact element 18 may be separately formed from a material and disposed between the surfaces of themounting shell 14, or theimpact elements 18 may be formed from a unitary sheet of material disposed between the surfaces of themounting shell 14. The unitary sheet of material forming theimpact elements 18 may be coextensive with the materials forming the surfaces of the mountingshell 14, or the unitary sheet may extend through only a portion of the mountingshell 14. Each mountingshell 14 includes a plurality ofimpact elements 18 formed adjacent thefirst end 28 of the mountingshell 14 and evenly distributed across a circumference of the mountingshell 14. Favorable results have been obtained with mountingshells 14 having eight impact elements 18 (as shown inFIGS. 1 , 2, 5, and 6), but any number ofimpact elements 18 may be formed in the mountingshells 14. Eachimpact element 18 is formed from one of a ductile metal or a polymeric material, such as a fiber reinforced plastic, for example, having a yield strength less than a yield strength of the material(s) forming the mountingshells 14 and thevessel shells 16. It is understood that the glass fibers of theimpact element 18 may be randomly dispersed throughout the polymer, or the glass fibers may be aligned perpendicular to a longitudinal axis L of thepressure vessel 12 or parallel thereto. Favorable results have been obtained byimpact elements 18 having glass fibers aligned perpendicular to the longitudinal axis L of thepressure vessel 12. The perpendicularly aligned fibers of theimpact elements 18 provide sufficient strength necessary to bear loads in the direction perpendicular to the longitudinal axis L. Theimpact element 18 may be formed as an intermediate layer of the entire mountingshell 14, or theimpact element 18 may be an intermediate layer of only a portion of the mountingshell 14. The mountingshell 14 includes one of theapertures 36 across which theimpact element 18 is disposed. Each of theapertures 36 has a longitudinal axis A substantially parallel to the longitudinal axis L of thepressure vessel 12, but the longitudinal axis A may be perpendicular to the longitudinal axis L of thepressure vessel 12. The longitudinal axis A of the aperture is also the longitudinal axis of theimpact element 18 disposed therethrough. In another embodiment of the invention, theaperture 36 and theimpact element 18 are formed in thevessel shell 16 rather than the mountingshell 14. However, it is desirable to form the impact element in the mountingshell 14 to facilitate rapid replacement of a mountingshell 14 in need of replacement. In yet another embodiment of the invention, theimpact element 18 as described hereinabove is formed in both thevessel shell 16 and the mountingshell 14 with theapertures 36 of eachshell - To assemble the
storage system 100, thesecond end 28 of the mountingshell 14 and thefirst end 32 of thevessel shell 16 are coupled together by a coupling means 38. As shown inFIGS. 1 and 2 , a portion of thesecond end 28 of the mountingshell 14 overlaps a portion of thefirst end 32 of thevessel shell 16. As best shown inFIG. 4 , the coupling means 38 extends through theaperture 36 to couple thevessel shell 16 to the mountingshell 14. At least a portion of the coupling means 38 abuts theimpact element 18, or, as shown inFIG. 4 , the coupling means 38 may be disposed through theimpact element 18. In the present embodiment, the coupling means 38 is a rivet, but the coupling means 38 may be a bolt, screw, or other coupling means suitable for coupling thevessel shell 16 to the mountingshell 14 and abutting theimpact element 18. A pair of mountingsystems 10 is disposed on afirst end 40 of thepressure vessel 12 with a substantial portion of thevessel shell 16 of each mountingsystem 10 abutting thepressure vessel 12. One of the clampingelements 20 is then disposed over a portion of the second ends 34 of eachvessel shell 16 to couple the mountingsystems 10 to thefirst end 40 of thepressure vessel 12. Another pair of mountingsystems 10 is disposed on asecond end 42 of thepressure vessel 12 with another of the clampingelements 20. Theflanges 30 of the first ends 24 of the mountingshells 14 of each mountingsystem 10 are coupled to acorresponding side rail 31 of thevehicle 26. When mounted to thevehicle 26, the longitudinal axis A of each of theimpact elements 18 and the longitudinal axis L of thepressure vessel 12 are perpendicular to a longitudinal axis V of thevehicle 26. It is understood that the longitudinal axis A of each of theimpact elements 18 and the longitudinal axis L of thepressure vessel 12 may be parallel to the longitudinal axis V of thevehicle 26, as desired. Alternatively, the mountingsystems 10 and clampingelements 20 may be pre-assembled and then pressed or otherwise mounted on thepressure vessel 12. Furthermore, the mountingshell 14 and/or thevessel shell 16 may include holes formed therein (not shown) to facilitate cables or other mounting hardware therethrough or to facilitate a flow of air therethrough. The size and number of holes may vary based on the contents of thepressure vessel 12 and the load(s) on theshells shells systems 10 may also vary. - In the event of a side impact event, a force on a side of the
vehicle 26 causes the side rails 31 on the side of thevehicle 26 to impart a force on the mountingshells 14 of the mountingsystems 10 coupled thereto and to thefirst end 40 of thepressure vessel 12. It is understood that a side impact event includes any impact event on thevehicle 26 that imparts any force on the vehicle in a direction parallel to the longitudinal axis L of thepressure vessel 12 and perpendicular to the longitudinal axis V of thevehicle 26. If the force on the mountingshells 14 is less than the impact strength of theimpact elements 18, theimpact elements 18 may elastically deform. If the force on the mountingshells 14 is greater than the yield strength of theimpact elements 18, the force causes the coupling means 38 to impart a force on theimpact elements 18, thereby causing the rupture of theimpact elements 18. The rupturing of theimpact elements 18 facilitates the movement of the mountingshells 14 toward thevessel shells 16, and at least a portion of the force from the side impact event is absorbed by the mountingsystems 10 andimpact elements 18. Once theimpact elements 18 are ruptured through, the coupling means 38 will abut a portion of the mountingshells 14 on an opposite end of theaperture 36, and the portions of theshells impact elements 18 are ruptured through and if the force of the side impact is sufficient, the force from the side impact event is distributed through thepressure vessel 12 and to the mountingsystems 10 disposed on thesecond end 42 of thepressure vessel 12. If the force on thevessel shells 16 disposed on thesecond end 42 is less than the impact strength of theimpact elements 18 thereof, theimpact elements 18 may elastically deform. If the force on thevessel shells 16 is greater than the yield strength of theimpact elements 18, theimpact elements 18 will impart a force on the coupling means 38, causing theimpact elements 18 to rupture, thereby facilitating the movement of thevessel shells 16 toward the mountingshells 14. Once theimpact elements 18 are ruptured through, the coupling means 38 will abut a portion of the mountingshells 14 on an opposite end of theaperture 36 and the portions of theshells impact elements 18 have yield strengths less than the yield strengths of theshells impact elements 18 are adapted to be frangible and to rupture and absorb at least a portion of the force from the side impact event to militate against damage to thepressure vessel 12 and/or theshells shells pressure vessel 12 is minimized. -
FIG. 7 illustrates astorage system 700 substantially similar to thestorage system 100 described hereinabove except as explained hereinbelow. Thestorage system 700 includes a plurality of mountingsystems 10 and apressure vessel 12 according to another embodiment of the invention. Each mountingsystem 10 includes a mountingshell 14, avessel shell 16, and animpact element 18. In the embodiment shown, a pair of mountingsystems 10 is fixed to each end of thepressure vessel 12 by a pair of clampingelements 44. The clampingelements 44 are rings adapted to couple the mountingsystems 10 to thepressure vessel 12 to militate against relative movement between the mountingsystems 10 and thepressure vessel 12. The clampingelements 44 include an inner surface having abeveled edge 46 adapted to engage and mate with a correspondingbeveled edge 48 of the mountingsystems 10, thereby coupling the mountingsystems 10 to thepressure vessel 12. It is understood that each of the clampingelements 44 may be an elongate member having ends adapted to be mechanically fixed together to form theclamping elements 44 around the mountingsystems 10. The beveled edges 44, 46 cooperate to militate against the movement of the clampingelements 44 toward the mountingshells 14 at each end of thepressure vessel 12. - To assemble the
storage system 700, asecond end 28 of the mountingshell 14 and afirst end 32 of thevessel shell 16 are coupled together by a coupling means 38. A portion of thefirst end 32 of thevessel shell 16 overlaps a portion of thesecond end 28 of the mountingshell 14. The coupling means 38 extends through theaperture 36 to couple thevessel shell 16 to the mountingshell 14. At least a portion of the coupling means 38 abuts theimpact element 18. A pair of mountingsystems 10 is disposed on afirst end 40 of thepressure vessel 12 with a substantial portion of thevessel shell 16 of each mountingsystem 10 abutting thepressure vessel 12. One of the clampingelements 44 is then disposed over a portion of the second ends 34 of eachvessel shell 16 with thebeveled edges systems 10 to thefirst end 40 of thepressure vessel 12. Another pair of mountingsystems 10 is disposed on asecond end 42 of the pressure vessel with another of the pair of clampingelements 44. Theflanges 30 of the first ends 24 of the mountingshells 14 of each mountingsystem 10 are then coupled to a corresponding side rail (not shown) of a vehicle (not shown). When mounted to thevehicle 26, the longitudinal axis A of each of theimpact elements 18 and the longitudinal axis L of thepressure vessel 12 are perpendicular to a longitudinal axis of thevehicle 26. It is understood that the longitudinal axis A of each of theimpact elements 18 and the longitudinal axis L of thepressure vessel 12 may be parallel to a longitudinal axis V of thevehicle 26, as desired. - In the event of a side impact event, a force on a side of the
vehicle 26 causes the side rails 31 on the side of thevehicle 26 to impart a force on the mountingshells 14 of the mountingsystems 10 coupled thereto and to thefirst end 40 of thepressure vessel 12. It is understood that a side impact event includes any impact event on thevehicle 26 that imparts any force on thevehicle 26 in a direction parallel to the longitudinal axis L of thepressure vessel 12 and perpendicular to the longitudinal axis V of thevehicle 26. If the force on the mountingshells 14 is less than the impact strength of theimpact elements 18, theimpact elements 18 may elastically deform. If the force on the mountingshells 14 is greater than the yield strength of theimpact elements 18, the force causes the coupling means 38 to impart a force on theimpact elements 18, thereby causing the rupture of theimpact elements 18. The rupturing of theimpact elements 18 facilitates the movement of the mountingshells 14 toward thevessel shells 16, and at least a portion of the force from the side impact event is absorbed by the mountingsystems 10 andimpact elements 18. Once theimpact elements 18 are ruptured through, the coupling means 38 will abut a portion of the mountingshells 14 on an opposite end of theaperture 36, and the portions of theshells impact elements 18 are ruptured through and if the force of the side impact is sufficient, the force from the side impact event is distributed through thepressure vessel 12 and to the mountingsystems 10 disposed on thesecond end 42 of thepressure vessel 12. If the force on thevessel shells 16 disposed on thesecond end 42 of thepressure vessel 12 is less than the impact strength of theimpact elements 18 thereof, theimpact elements 18 may elastically deform. If the force on thevessel shells 16 is greater than the yield strength of theimpact elements 18, theimpact elements 18 will impart a force on the coupling means 38 causing theimpact elements 18 to rupture, thereby facilitating the movement of thevessel shells 16 toward the mountingshells 14. Once theimpact elements 18 are ruptured through, the coupling means 38 will abut a portion of the mountingshells 14 on an opposite end of theaperture 36 and the portions of theshells impact elements 18 have yield strengths less than the yield strengths of theshells impact elements 18 are adapted to be frangible and to rupture and absorb at least a portion of the force from the side impact event to militate against damage to thepressure vessel 12 and/or theshells shells pressure vessel 12 is minimized. - From the foregoing description, one ordinarily skilled in the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, make various changes and modifications to the invention to adapt it to various usages and conditions.
